Problem 11PE
As a woman walks, her entire weight is momentarily placed on one heel of her high-heeled shoes. Calculate the pressure exerted on the floor by the heel if it has an area of 1.50 cm2 and the woman’s mass is 55.0 kg. Express the pressure in Pa. (In the early days of commercial flight, women were not allowed to wear high-heeled shoes because aircraft floors were too thin to withstand such large pressures.)

Problem 11PE
As a woman walks, her entire weight is momentarily placed on one heel of her high-heeled shoes. Calculate the pressure exerted on the floor by the heel if it has an area of 1.50 cm2 and the woman’s mass is 55.0 kg. Express the pressure in Pa. (In the early days of commercial flight, women were not allowed to wear high-heeled shoes because aircraft floors were too thin to withstand such large pressures.)
ANSWER:
Step 1 of 2:
The pressure exerted is nothing but the force applied to the given unit area. If a woman walks with her high-heeled shoes, the whole weight of the woman is placed on a small area at that instantaneous time. A huge pressure is applied on the floor. The area of the shoe and the mass of the woman are provided. We are going to calculate the pressure on the floor.
The area of the heel
The mass of the woman
The acceleration due to gravity
